Preheat oven to 350 degrees. Add Chebe mix and 1/3 cup of shredded cheddar cheese to food processor. Pulse 5-6 times to further break down the shreds of cheese and incorporate into the mix. 

Next, add the 2 tbsp of oil, and pulse until fully blended. Add eggs and repeat. 

Lastly, stream the 3 tsbp of water into the dough while the food processor is on. It should come together in a small ball of dough. There will likely be residual mix in the bottom of the food processor bowl. 

Dump the dough out onto a flat surface, and sprinkle any remaining powder mix on top and incorporate into dough. Knead until a soft but firm ball of dough is reached. Set aside and cover with plastic wrap to prevent drying out. 

Meawhile, prepare the filling. Dice onions into small pieces, and cook in a hot skillet with the ground beef. (I use ground sirloin.) 

Season meat with spices and gluten free Worcestershire sauce. (In the United States, Lea and Perrins contains no gluten.) Set aside. (Some other recipes add ketchup to the mix, the create a sauce. I have not done so, but you can try it if you like!) 

Grab the ball of dough and portion it into 12 equal pieces. (I used my scale and they weighed approx. 35 grams each.) I used a tortilla press, lined with plastic (parchment works too) to press the dough balls into uniform circles. I then sprinkled mine with a bit of sesame seeds (completely optional).(Depending on the non-stick nature of your muffin tin, you may want to spray the wells with a bit of vegetable oil.) 

Then I pressed the circle of dough, seeds down, into the muffin tin. Use fingers to firmly press the dough evenly into the muffin well. 

Fill each muffin cup with cooked beef. Feel free to overfill and press down, as the beef will settle while cooking. Bake in oven for 25 minutes. 

After 25 minutes, remove from oven, and top each cheeseburger muffin cup with two thin sliced squares of cheese. Return to oven for 2-3 minutes to melt cheese. 

Remove from oven and top with desired condiments, such as ketchup and mustard, lettuce or pickles. Best served hot. Should they cool, they can be rewarmed in the microwave.
